100 THE PRACTICE OF VETERINARY MEDICINE. 



exudation may now be seen also. The general health of 

 the animal, after a considerable time, begins to suffer : he 

 becomes emaciated, feverish, and in some cases death takes 

 place. Mange, while accompanied by a great deal of irrita- 

 tion of the skin, is greatly exceeded in this respect by eczema. 

 A recollection of this fact will assist very materially in 

 making the differential diagnosis between the two diseases. 

 Treatment. — The first step to be taken in the treatment 

 of mange is, of course, the removal of the cause — destroy 

 the parasites. However, the destruction of the mange 

 parasite is a matter more easily spoken of than effected. 

 External applications should be used, and are, of course, of 

 greater importance than constitutional treatment, though 

 the latter may be necessary in some cases. One of the best 

 applications is as follows : Acid, carbol. 3i., aquae O.i. 

 This mixture must be used carefully, and not applied over 

 the whole of the body at one time, but only over a part of 

 the body. Wash the parts well with soap and tepid water 

 before using the mixture. It is always good practice to 

 have the animal clipped before making any application, 

 and it is in many cases absolutely necessary to clip the body. 

 Ungt. hydrarg. is also a useful application, but requires to be 

 used with caution. Another recipe is as follows : 01. picis, 

 ol. lini, sulph. flor., partes equales. This is a very old as well 

 as a very useful recipe, and the only objection to its employ- 

 ment is, that it is rather unpleasant to use, gumming the 

 hair and clogging up the pores. Another preparation highly 

 thought of by many practitioners is the following : Sulph. flor. 

 5i. — 5ii., adeps prsep. 5vi. — ^i. Sulphur iodide is also of very 

 great value in the treatment of this, as well as many other 

 skin diseases. The animal should be removed from the stall 

 or place he has been occupying. After his removal the place 

 should be thoroughly cleansed by washing with hot water 

 containinsr carbolic acid. The same method is to be
